The rumor is that HTC's rumored One X 5 "phablet" (hate that term) will become the next Google Nexus device under the name Nexus 5.
Highlights:
Snapdragon S4 Pro chipset
1080p display (I really don't believe that)
12MP main camera
2MP front-facing camera
64GB internal storage
2,500mAh
LTE connectivity
